摘要： A magnetorheological (MR) piston ring includes an MR-piston-ring body disposable within a cylinder of an MR damper along a central longitudinal axis. The MR-piston-ring body has a radially inner surface defining a boundary of a longitudinally-extending MR passageway. The MR-piston-ring body includes a surface portion which is slidingly engagable with the cylinder and which has first and second longitudinal ends. The surface portion includes at least one surface groove each defining a secondary MR passageway and extending between the first and the second longitudinal ends. The surface groove is substantially straight and tilted with respect to a line drawn on the surface portion parallel to the central longitudinal axis. An MR damper including the MR piston ring is also described.

摘要： A magnetorheolgical (MR) damper includes a piston assembly having a primary channel disposed along a longitudinal axis and contained in a cylinder. MR fluid is also contained in the cylinder. The piston assembly having a primary channel, or primary channel MR piston assembly, includes a piston body having a first end axially spaced from a second end and defining a hole therethrough. The primary channel is defined in an outer body surface of the piston body from the hole at the second end to a coil groove in the outer body surface about the axis. A secondary channel is defined in the outer body surface from the coil groove towards the first end to improve MR damper force performance at low primary channel MR piston assembly velocities.

摘要： A monotube shock absorber assembly includes a housing (20), a gas cup (32) slidably disposed in the interior (28) of the housing (20), and a piston (42) slidably disposed in the interior (28) of the housing (20) to define an oil compression chamber (48) between the piston (42) and the gas cup (32). A cushion (58) engages one of the piston (42) and the gas cup (32) and extends axially into the oil compression chamber (48) for intermittent contact with the other of the piston (42) and the gas cup (32). The cushion (58) is a resilient material and deforms in response to the cushion (58) contacting the other of the piston (42) and the gas cup (32). In a preferred embodiment, the cushion (58) defines a central opening (60) for decreasing the axial stiffness of the cushion (58) and engages the gas cup (32) for intermittent contact with the piston (42). In a preferred embodiment the cushion (58) presents an anchor (72) for retaining the cushion (58) against the piston (42) for intermittent contact with the gas cup (32).

摘要： The invention relates to a hydraulic damper, in particular for the suspension system of a motor vehicle, comprising a tube filled with working fluid; a piston assembly slidably positioned inside the tube; a fluid compensation chamber located outside of the tube, and a base valve assembly at the end of the tube for controlling the flow of working fluid between the tube and the compensation chamber. A compression valve module added between the piston assembly and the base valve assembly allows the damping to increase during extremely fast compression strokes without modification of the other damper components, affecting neither tuning options nor performance in a normal operating range of piston velocities.

摘要： Method and apparatus for controlling the front and rear wheel braking system of a road-going mass-produced motor car or automobile enables provision of brake-by-wire facilities utilizing an electrically-powered servo motor to generate brake-operating thrust which is applied to the interleaved friction elements and twin discs of a disc brake having axially slideable discs and a fixed caliper and disc and friction element-attitude control structure. The brake is of spot-type disc brake construction and the servo motor applies less brake-actuating thrust than is required for a comparable fixed disc and floating caliper construction.

摘要： A system and method of controlling engine vibration mounted within a vehicle including at least one hydraulic mount, each mount including a fluid chamber. A pair of accelerometers sense relative acceleration across the mount between the engine and the frame and generate a relative acceleration signal. A control unit is electrically connected to the accelerometers. The control unit is adapted to generate an electronic control signal in response to the relative acceleration signal. The control device is responsive to the electric control signal for controlling the damping force of the hydraulic mount. A control algorithm calibrates the control unit such that maximum vibration damping occurs at and around the engine resonance bounce frequency.
